Abstract
The utility model discloses a disc brake type vehicle speed sensing device which comprises a frame, a hub, a disc brake, a permanent magnet and a Hall element, wherein the hub is rotatably mounted on the frame through a bearing; the disc brake is fixed on the outer side of the hub; the permanent magnet is mounted on the disc brake; the Hall element is mounted on the frame; and the mounting position of the Hall element on the frame corresponds to the permanent magnet on the disc brake type vehicle speed sensing device. In the utility model, the permanent magnet and the Hall element are mounted on the disc brake and the frame respectively and face to each other at an interval, the vehicle speed is detected by the Hall element sensing the magnetic field change of the permanent magnet, the structure is simple, and the response is sensitive.
Description
Technical field
The utility model relates to a kind of self-propelled vehicle, particularly relates to a kind of disc brake formula speed of a motor vehicle induction installation.
Background technology
General motor bike is shown in the speed of a motor vehicle on the instrument carrier panel; The speed of a motor vehicle induction installation that is the wheel through being installed in motor bike is mostly reached; And speed of a motor vehicle induction installation was that main this mechanical type speed of a motor vehicle induction installation also has its shortcoming with the mechanical type in the past: (1) sensitivity is not enough: when the wheel of motor bike to slowly run; The beat of pointer amplitude of this instrument carrier panel is very little, even does not change.(2) reaction time is long: under the speed steep variation, the pointer of this instrument carrier panel can't change at once thereupon, and it is because due to the characteristic of the material of the inertia of physical construction itself and physical construction itself.
The utility model content
The purpose of the utility model is to provide a kind of sensitive disc brake formula speed of a motor vehicle induction installation.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The utility model is a kind of disc brake formula speed of a motor vehicle induction installation, and it comprises vehicle frame, wheel hub, disc brake, permanent magnet, Hall element; Described wheel hub is installed on the vehicle frame through bearing is rotatable, and disc brake is fixed on the outside of wheel hub; Permanent magnet is installed on disc brake, corresponding with the permanent magnet on the disc brake formula speed of a motor vehicle induction installation at installation Hall element and Hall element on the vehicle frame in the installation position on the vehicle frame.
The profile of described permanent magnet is circular, square, strip shape.
After adopting such scheme, because the utility model permanent magnet is installed in respectively on disc brake and the vehicle frame with Hall element, relative at interval, the changes of magnetic field of utilizing Hall element to respond to permanent magnet is detected the speed of a motor vehicle, and is simple in structure, be quick on the draw.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the three-dimensional exploded view that the utility model permanent magnet is installed in first embodiment on the disc brake;
Fig. 3 is the axonometric drawing that the utility model permanent magnet is installed in first embodiment on the disc brake;
Fig. 4 is the front elevation that the utility model permanent magnet is installed in second embodiment on the disc brake.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, first embodiment of the utility model disc brake formula speed of a motor vehicle induction installation, it comprises vehicle frame 1, wheel hub 2, disc brake 3, permanent magnet 4, Hall element 5.
Described wheel hub 2 is installed on the vehicle frame 1 through bearing is rotatable, and disc brake 3 is fixed on the outside of wheel hub 2; Circular permanent magnet 4 is installed on disc brake 3, corresponding with the permanent magnet 4 on the disc brake formula speed of a motor vehicle induction installation at installation Hall element 5 and Hall element 5 on the vehicle frame 1 in the installation position on the vehicle frame 1.
As shown in Figure 4, the profile of described permanent magnet 4 ' is a strip shape, is installed in the optional position of disc brake 3.
In addition, permanent magnet also can be square other shapes that waits.
The emphasis of the utility model just is: utilize the changes of magnetic field of Hall element induction permanent magnet to detect the speed of a motor vehicle.
The above; Be merely the utility model preferred embodiment; The installation position of permanent magnet on wheel hub can have multiple; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
